The approach is right on. Taking cues from Gigabyte and their windforce x3 cooler, under load, temps should be below 70 degrees and acoustically should be below 40db at least. Power consumption is already acceptable even if it isn't as efficient as Kepler.

As for the big elephant that i'm sure everyone will talk about, yes multi-GPU stuttering, AMD is working on a resolution that will come in or around a July driver drop.
